CHICAGO - Managers of an Illinois cleaning company have been charged with helping employees buy stolen Social Security numbers from an underground Chicago market.

The Chicago Tribune reported that two managers and 60 employees of Quality Service Integrity Inc. of Beardstown, Ill., were arrested Wednesday. The managers are alleged to have helped at least 25 employees buy stolen Social Security numbers.

They were arrested during a raid at a central Illinois meatpacking plant cleaned by Quality Service Integrity.

A federal affidavit alleged that the company managers sent prospective workers to Chicago to buy stolen identities, the Tribune reported.

Gerardo Dominguez-Chacon, the company manager, gave some of the workers Social Security numbers, the affidavit said.

Company employees who had been arrested earlier and agreed to wear recording devices helped with the investigation, the newspaper reported.
